ROTARY ENGINE.

SPECIFICATION forming part of Letters Patent No. 269,991, dated January 2, 1858. Application filed July 28, 1882. (No model.)

To all whom it may concern:

Be it knojwn that I, BENJAMIN T. BABBITT, of the city and county of New York, in the State of New York, have invented a certain new and useful Improvement in Rotary Engines, of which the following is a specification.

The object of my invention is to provide a very simple rotary engine in which there are no closely-working surfaces, which are liable to great wear, and which, by reason of such wear, frequently render theengineuseless.

My invention consists in the combination, with a rotary shaft and a wheel orV ianges thereon, of a circular series of buckets or pockets attached to thewheel or flangesl and each y Lprovided with two mouths or crilices opening in the same directiornand a stationary nozzle from which ajet of steam may issue continuously into one mouth or rilice of the several buckets in succession and impel the wheel by its impact against the back or bottom of the bucket, while the steam escapes from the other mouths or orilices of the buckets, and, by reacting-upon the closed backs or bottoms of the buckets, again 'acts to impel the wheel. I also combine with the above a stationair f jacket or case which iucloses the wheel and i bearings A retains the exhaust-steam; and at the bottom of thisjacket is an escape-pipe through which the exhaust and the water of condensation may escape. j

In the accompanying drawings, Figure l represents a perspective view of a portion of the wheel with itsbuckets and the steam-noz zie. Fig. 2 represents a detail sectional view of one ofthe buckets, and Fig. 3 represents a partly-sectional side view ofthe engine on a smaller scale.

Similar letters of reference designate corresponding parts in all the figures.

A designates a shaft which passesthrough in a stationary cylinder casing or jacket, B, wherein it is adapted to turn, and C U designate flanges which are secured at a little distance apart on said shaft, and form, in effect, a wheel.

D designates buckets or pockets, of which there may be any desired number, arranged in a circular series between the flanges or in the wheel, and E designates a stationary nozzle, to which a steam-pipe may be connected,

and which extends through the jacket or case in such position that the buckets D pass in close proximity to the end ofthe nozzle. The buckets here shown are U -shaped, as best shown in Fig. 2, and they may be composed of sheet metal, or in any other suitable manner. In this example of my invention theouter sides or walls of the buckets have ears or lugs a projecting from their sides, which pass through holes in the anges C, and may have their ends riveted to secure the anges together. Screws b may be inserted through the anges and into the buckets, and serve additionally to 6 5 Secure the buckets'in place. Each bucket D is divided by a partition, c, about midway ot' its width, so as to form in each buckettwo separate mouths or oritices, d d', side by side, and facing or opening in the same direction. The steam issuing from the nozzle E enters the mouths or orifices d, and, impinging againstr the closed backs or bottoms ofthe buckets, impels the wheel and shaft in the direction of the arrow in Figs. l and 3. As the wheel is turned thesteamenters the buckets successively and rotates the wheel at a Vuniform speed throughout its entire rotation. The steam escapes from the buckets through the' mouthsor orifices d', and, reacting upon the closed backs or bottoms of the bucket-s, serves additionally to turn the wheel.

The shaft A may have a pulley fixed upon it outside the jacket or casing B, from which power may be taken by a belt. casing E serves to retain the exhauststeam and prevents its escape into the atmosphere, and is sutiiciently larger in diameter than the wheel to afford a clear space around it.` The The jacket or steam and water of condensation escape from 9o the jacket or casing through an escape-pipe, e.

This engine is very simplein itsconstruetion. There are no parts which are liable to get out of order, and no surfaces which move in such close contact with .other surfaces as to create two mouths or orifices facing in the samedi- IOO reotion, and a nozzle for directing steam or 3. The combination ofthe shaftA,thei1anges other uid successively into the mouths or ori- G C, the U-shaped buckets D, each provided ices of the several buckets, substantially as with the partition c, and the nozzle E, suband for the purpose specified. stautially as specified.
